Why does the rule in urlManager not work?

Question

Yii

I make a sitemap, created a rule: 'sitemap.xml'=> array('sitemap/index', 'urlSuffix' => ''), if I go to site.com/sitemap.xml, then nothing in response, I get only a string like: "This XML file does not appear to have any style information associated with it. The document tree is shown below." It doesn't reach my controller and the view, what's wrong?
Here is the urlManager code:

'urlManager'=>array(
                        'class'=>'DLanguageUrlManager',
      'urlFormat' => 'path',
                        'showScriptName'=>false,
                        'urlSuffix' => '',
                            'rules'=>array(
                                
                                'sitemap.xml'=> array('sitemap/index', 'urlSuffix' => ''),
                                
                                'page/<id:\d+>/<alias:.*>/<platform:.*>' => 'page/index/',
                                'page/<id:\d+>/<alias:.*>' => 'page/index/',
                                'page/<id:\d+>' => 'page/index/',
                                'page' => 'page/index/',
                                
                                'review/<id:\d+>/<alias:.*>' => 'review/index/',
                                'review/<id:\d+>' => 'review/index/',
                                '<controller:\w+>/<id:\d+>' => '<controller>/index',
                                '<controller:\w+>/<action:\w+>/<id:\d+>' => '<controller>/<action>',
                                '<controller:\w+>/<action:\w+>' => '<controller>/<action>',
                                
                                
      ),
    ),

If you access the site.com/sitemap/index controller, then everything works.

Answer 1

Is there a sitemap.xml file in the web folder by any chance? :)

Answer 2

just try
'sitemap.xml'=> 'sitemap/index'
